RESUMO
BACKGROUND: Patients with traumatic intracranial hemorrhage and mild traumatic brain injury (mTIH) receive broadly variable care which often includes transfer to a trauma center, neurosurgery consultation and ICU admission. However, there may be a low risk cohort of patients who can be managed without utilizing such significant resources. OBJECTIVE: Describe mTIH patients who are at low risk of clinical or radiographic decompensation and can be safely managed in an ED observation unit (EDOU). METHODS: Retrospective evaluation of patients age≥16, GCS≥13 with ICH on CT. Primary outcomes included clinical/neurologic deterioration, CT worsening or need for neurosurgery. RESULTS: 1185 consecutive patients were studied. 814 were admitted and 371 observed patients (OP) were monitored in the EDOU or discharged from the ED after a period of observation. None of the OP deteriorated clinically. 299 OP (81%) had a single lesion on CT; 72 had mixed lesions. 120 patients had isolated subarachnoid hemorrhage (iSAH) and they did uniformly well. Of the 119 OP who had subdural hematoma (SDH), 6 had worsening CT scans and 3 underwent burr hole drainage procedures as inpatients due to persistent SDH without new deficit. Of the 39 OP who had cerebral contusions, 3 had worsening CT scans and one required NSG admission. No patient returned to the ED with a complication. Follow-up was obtained on 81% of OP. 2 patients with SDH required burr hole procedure >2weeks after discharge. CONCLUSIONS: Patients with mTIH, particularly those with iSAH, have very low rates of clinical or radiographic deterioration and may be safe for monitoring in an emergency department observation unit.

INTRODUCTION: Traumatic intracranial hemorrhage (TIH), brain injury with radiographic hemorrhage, is a common emergency department (ED) presentation, and encompasses a wide range of clinical syndromes. Patients with moderate and severe neurotrauma (Glasgow Coma Scale [GCS] < 13) with intracranial hemorrhage require care at a trauma center with neurosurgical capabilities. However, many patients with mild traumatic intracranial hemorrhage (mTIH), defined as radiographic bleeding and GCS ≥ 13, do not require operative intervention or intensive care unit monitoring, but are still routinely transferred to tertiary care centers. We hypothesized that a significant proportion of patients are managed non-operatively and are discharged within 24 hours of admission. METHODS: This was a retrospective, observational study of consecutive patients age ≥ 16 years, GCS ≥ 13 who were transferred to an urban, medical school-affiliated, 100,000 annual visit ED over a seven-year period with blunt isolated mTIH. The primary outcome was discharge within 24 hours of admission. We measured rates of neurosurgical intervention, computed tomography hemorrhage progression, and neurologic deterioration as well as other demographic and clinical variables. RESULTS: There were 1079 transferred patients with isolated mTIH. Of these, 92.4% were treated non-operatively and 35.8% were discharged within 24 hours of presentation to the tertiary ED. Patient characteristics associated with rapid discharge after transfer include a GCS of 15 (odds ratio [OR] 2.9, 95% confidence interval [CI], 1.9 - 4.4), subdural hematoma ≤ 6mm (OR 3.1, 95% CI, 2.2 - 4.5) or the presence of an isolated subarachnoid hemorrhage (OR 1.7, 95% CI, 1.3 - 2.4). Of patients with length of stay < 24 hours, 79.8% were discharged directly from the ED or ED observation unit. CONCLUSION: Patients transferred to tertiary care centers are frequently discharged after brief observation without intervention. Risk can be predicted by clinical and radiographic data. Further prospective research is required to determine a safe cohort of patients who could be managed at community sites.

INTRODUCTION: Similar to spontaneous aortic dissection, traumatic aortic dissection is diagnosed with a careful history and physical exam, chest radiograph, and ultimately, dedicated aortic imaging. The diagnosis of spontaneous aortic dissection may be aided by using the serum D-dimer test. The use of D-dimer for diagnosing aortic injury in the setting of blunt trauma has not previously been reported. PRESENTATION OF CASE: We present a case of aortic dissection in a 61-year-old male diagnosed when the patient presented with chest pain after blunt chest trauma. DISCUSSION: The patient had no known history or risk factors for aortic disease. None of the classic findings were present by history, physical examination or chest radiograph and the diagnosis was made as the result of an elevated D-dimer. We discuss how the D-dimer test fortuitously led to the diagnosis in this case, and the implications. CONCLUSION: D-dimer could be helpful in diagnosing aortic injuries in low-risk chest trauma patients.
RESUMO
BACKGROUND: Current standard of care for patients with traumatic intracranial hemorrhage (TIH) includes neurosurgical consultation and/or transfer to a trauma center with neurosurgical backup. We hypothesize that a set of low-risk criteria can be applied to such patients to identify those who may not require neurosurgical evaluation. METHODS: This is a cross-sectional study of consecutive emergency department patients in 2009 and 2010 with TIH on computerized tomographic scan owing to blunt head trauma. Patients presented to an urban academic Level I trauma center (volume, 92,000) were older than 15 years and had a Glasgow Coma Scale (GCS) score of 13 or greater. Charts were abstracted using a standardized data form by two emergency physicians. Our principal outcome was deterioration represented by a composite of neurosurgical intervention, clinical deterioration, or worsening computerized tomographic scan result. RESULTS: During the study period, 404 patients were seen with TIH and met our inclusion criteria, and 48 of those patients (11.8%) deteriorated. Patients with isolated subarachnoid hemorrhage, were less likely to deteriorate (odds ratio [OR], 0.08; 95% confidence interval [CI], 0.011-0.58). Characteristics associated with deterioration were subdural hematomas (OR, 2.63; 95% CI, 1.198-5.81) or presenting GCS of less than 15 (OR, 2.12; 95% CI, 1.01-4.43).The use of anticoagulant medications or antiplatelet agents were not associated with deterioration for warfarin, aspirin, or clopidogrel; however bleeding diatheses were corrected with vitamin K, fresh frozen plasma, and platelets as necessary. CONCLUSION: Patients with isolated traumatic subarachnoid hemorrhage are at low risk for deterioration. These individuals may not need neurosurgical consultation or transfer to a trauma center where neurosurgical backup is available. Those patients with subdural hematoma or a GCS of less than 15 have a higher risk of deterioration and require neurosurgical evaluation. LEVEL OF EVIDENCE: Therapeutic/care management, level IV.
